Potential & Kinetic Energy

Front

What is Kinetic Energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and the speed at which it is moving.

Front

What is Potential Energy?

Back

Potential energy is the stored energy of an object due to its position or state. It can be gravitational, elastic, or chemical.

What type of energy is present in a baseball held by a pitcher?

Back

Potential energy.

Front

What is Chemical Potential Energy?

Back

Chemical potential energy is the energy stored in the bonds of chemical compounds, like wood, batteries, and food.

Front

What is Gravitational Potential Energy?

Back

Gravitational potential energy is the energy an object possesses because of its height above the ground, calculated as weight times height.

Front

What is an example of Kinetic Energy?

Back

A moving car, a flowing river, or a flying bird.

Front

What is an example of Potential Energy?

Back

A stretched rubber band, a book on a shelf, or water stored in a dam.

Front

How does mass affect Kinetic Energy?

Back

Kinetic energy increases with the mass of the object; more mass means more energy when moving.
